LETCHER COUNTY, Ky. (WYMT) - Rescue crews found three hikers lost on Pine Mountain Tuesday night.Pine Mountain Search and Rescue received a call around 10 p.m. and responded to Bad Branch Falls."They entered the trail at the Bad Branch parking lot and they hiked up to High Rock," said Sam Adams, the Assistant Chief of Pine Mountain Search and Rescue. "It got dark on them, they didn't have a flashlight and they lost their bearings. They called 911 and their cell phone went dead, so they didn't have a light there either."Adams said the rescue crews were able to locate the hikers just before 11:30."They had done what they should've done," said Adams. "They stopped where they were, they didn't move around, they stayed in one spot and built a fire. Our people smelled the smoke and followed it until they saw the fire and that's how they found them."Adams said the three hikers began their hike around five on Tuesday evening. Which did not give them enough time to complete the trail before sunset.Right now trails at Bad Branch Falls don't close until six in the evening but officials say you should begin your hike way before that. In fact, if you're hiking up to High Rock, they suggest that you give yourself six to eight hours in order to complete your hike.
